Which of the following is an open loop control system?
Which of the following is an example of an open loop system?
When deriving the transfer function of a linear element
Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?
Which signal will become zero when the feedback signal and reference signal are equal?
A 500 mA voltmeter is specified to be accurate with ± 2%. Then, what is the limiting error when instrument is used to measure 300 mA?
Poles are the complex frequencies of a transfer function where the response becomes
Consider the following statements with respect to the feedback from the control systems: 1. The feedback can improve stability or be harmful to stability if it is not properly applied. 2. The feedback can always improve stability. 3. In many situations, the feedback can reduce the effect of noise and disturbance on system performance. 4. In general, the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located. Select the correct statements.
A control system in which the control action is somehow dependent on the output is known as -
How many poles does the following function have? \(F\left( s \right) = \frac{{{s^3} + 2s + 1}}{{{s^2} + 3s + 2}}\)
What is the name of the control mechanism in which output has no influence on input?
